On Global Warming Alarmists and True Believers

I think that I'm just going to quote Jonathan Swift on this one, folks - "It is useless to attempt to reason a man out of a thing he never reasoned into." The fact that I could tell Mr. Gore, "HELLO, by 400 ppm, CO2 has already absorbed pretty much all of the infrared energy that it can, and that even if you doubled it to 800 ppm (or even tripled it to 1,200 ppm), the warming effects would undoubtedly be paltry", and the fellow would simply tune me out, etc..
